Layered screening device with magnetic adsorption function for pyrite ore processing

Abstract

A layered screening device with a magnetic adsorption function for pyrite ore processing, disclosed by the present invention, comprises a screening box, a feeding port formed in the top end of the screening box and discharging ports formed in the side end and the bottom end of the screening box; a fixing plate is fixedly installed on the inner wall of the screening box, and a guide plate slidably connected with the inner wall of the screening box is arranged in the screening box; a telescopic rod is fixedly installed on the inner wall of the screening box, and a screening plate abutting against the inner wall of the screening box is arranged at the top end of the telescopic rod. According to the layered screening device with the magnetic adsorption function for pyrite ore processing, through the cooperation of the guide plate, the screening plate and a permanent magnet, ore is screened after being magnetically adsorbed, and the follow-up processing operation is facilitated; and meanwhile, through the cooperation of a vibration assembly, an auxiliary discharging assembly, a quantity control assembly and a collecting assembly, the continuous and stable work in the ore flowing process is ensured, the falling amount of the ore is controlled, and the stability and continuity of the subsequent magnetic attraction treatment are ensured.

Description

technical field [0001] The invention belongs to the technical field of pyrite ore processing, and in particular relates to a layered screening device for pyrite ore processing with a magnetic adsorption function. Background technique [0002] Pyrite, also known as pyrite, pyrrhotite, marcasite, is an important chemical mineral raw material, mainly used in the manufacture of sulfuric acid, and partly used in chemical raw materials to produce sulfur and various sulfur compounds. Rubber, papermaking, textiles, food, matches and other industries and agriculture have important uses. At present, in the acid production process of pyrite raw materials, the raw materials need to be processed in multiple steps, among which the screening of raw materials is the most important. An important step, but because the crushed ore contains metal substances, it is necessary to screen and remove the metal substances in the ore at this time, but at present, the crushed ore is generally directly p...
